Lee SH, et al. - Researchers here determined the potential utility of the neutrophil-to-lymphocyte ratio (NLR) as a predictor of acute infarction in acute vertigo patients without neurologic and computed tomography (CT) abnormalities. Among patients with acute vertigo in an Emergency Department, a combination of NLR > 2.8 and the absence of horizontal nystagmus was sufficiently specific for acute infarction; thus, further testing with magnetic resonance imaging (MRI) was indicated. The need for further testing could not be ruled out with NLR < 2.8 by itself or combined with the presence of horizontal nystagmus.
